gcc-3.0.2 + hash_map<string,int> compilation problems

[Matthew Sundling <sundlm at cs dot wisc dot edu>]

I have been trying to compile an extremely simple program that
uses a hash_map<string, int>.  I can't quit figure out what the
errors are telling to supply to the STL container to satisfy it.

Thanks for any insight you might have:

[---------------------------------------------------------------]
My program:

#include <iostream>
#include <string>
#include <ext/hash_map>

int main () {
  std::hash_map<std::string, int > str_hash;
  str_hash["text"] = 1;
  std::cout << str_hash["test"] << std::endl;
  return 0;
}

My gcc output:

>, 
_EqualKey = std::equal_to<std::string>,
